With Mitt Romney now the presumptive Republican presidential nominee, speculation has quickly shifted to possible running mates. So Rasmussen Reports has begun testing the waters on some of the more prominent names being mentioned as vice presidential candidates.

New Jersey’s outspoken Governor Chris Christie is the best liked of the first group of five, edging out former Senator Rick Santorum who just ended his presidential bid. Our latest national telephone survey of Likely U.S. Voters shows that Christie is viewed favorably by 43% and unfavorably by 35%. That includes 21% with a Very Favorable opinion of him and 16% with a Very Unfavorable one. But one-in-five voters (22%) don’t know enough about Christie to voice any opinion.

The survey of 1,000 Likely Voters was conducted on April 10-11, 2012 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
